According to GlobalData’s company profile on ENEOS, Hydrocarbon redistribution reaction catalysts was a key innovation area identified from patents. ENEOS's grant share as of July 2024 was 44%. Grant share is based on the ratio of number of grants to total number of patents.

The granted patent US12060378B2 presents a solid catalyst component specifically designed for olefin polymerization. This catalyst comprises titanium, magnesium, halogen, and an internal electron-donating compound. Notably, the internal electron-donating compound includes two distinct components: one with a phthalic acid ester structure and another that contains two or more ether or ester groups, excluding the phthalic acid ester structure. The mass percentage of the second electron-donating compound in the catalyst is specified to be between 0.5% and 1.5%. The patent also outlines a method for producing this solid catalyst component, which involves a sequential contact process with dialkoxy magnesium, a tetravalent titanium halogen compound, and the two types of electron-donating compounds.

In addition to the solid catalyst component, the patent details methods for producing a catalyst for olefin polymerization by combining the solid catalyst with an organoaluminum compound. The methods include the option to incorporate an external electron-donating compound to enhance the catalyst's performance. Furthermore, the patent describes a process for polymerizing olefins using the catalysts produced through these methods. Overall, the claims emphasize the innovative composition and production techniques of the catalyst, which aim to improve the efficiency and effectiveness of olefin polymerization processes.
